The goal is to ensure quality for a period of time after you buy it. That can be several days to several weeks, depending on the item. For instance, milk, assuming proper refrigeration, should last five to seven days past its sell-by date before turning sour.
An autoencoder is a neural network that is trained in an unsupervised fashion. The goal of an autoencoder is to find a more compact representation of the data by learning an encoder, which transforms the data to their corresponding compact representation, and a decoder, which reconstructs the original data.
Introduction to Motor Drives & Encoders Aâ3 Introduction to Motor Drives and Encoders What is an Encoder and How Does It Connect to the HSC? The word encoder can be a confusing term to those who have never used them. There are many types of encoders and the word itself can have as broad or narrow of a definition as a particular application might dictate. We will limit our discussion here to incremental encoders.
